2 Page 2 of 6 2 Industry terms and vocabulary applicable to reel-fed production processes must be used during assessment against this unit standard. 3 Definitions print industry includes all sectors involved in print and packaging industries including pre-production, production, and post-production activities, suppliers and distributors. The sectors include graphic pre-press, digital output sheet-fed, reel-fed, screen, binding and finishing, fibreboard packaging; production processes refer to offset, letterpress, flexographic and gravure; workplace practices refer to the documented procedures for the machine and/or workplace. Elements and performance criteria Element 1 Demonstrate knowledge of halftones for reel-fed printing. 1.1 Use of halftones is described in terms of reproducing an original copy. 1.2 Halftone screen rulings and angles are described for the different kinds of substrates and the reel-fed production process/es being undertaken in the workplace. processes (any of) offset, letterpress, flexo, gravure. Element 2 Demonstrate knowledge of image carriers used for reel-fed printing. image carriers plates or cylinders; processes (any of) offset, letterpress, flexographic, gravure. 2.1 Procedures for making image carriers are explained in terms of the reel-fed production process/es used in the workplace. 2.2 Materials used to make image carriers are described in terms of the reel-fed production process/es used in the workplace.

Element 11 Demonstrate knowledge of colour theory and use colour terms Colour theory is explained in terms of additive colours (red, green and blue light) Colour theory is explained in terms of subtractive colours (cyan, magenta and yellow pigments) s of visual colour, red, green, blue (RGB) and cyan, magenta, yellow, black (CMYK) are explained in terms of their relationships to each other Correct viewing conditions are explained in terms of their importance to colour matching. Please note Providers must be accredited by NZQA, or an inter-institutional body with delegated authority for quality assurance, before they can report credits from assessment against unit standards or deliver courses of study leading to that assessment. Industry Training Organisations must be accredited by NZQA before they can register credits from assessment against unit standards. Accredited providers and Industry Training Organisations assessing against unit standards must engage with the moderation system that applies to those standards. Accreditation requirements and an outline of the moderation system that applies to this standard are outlined in the Accreditation and Moderation Action Plan (AMAP). The AMAP also includes useful information about special requirements for organisations wishing to develop education and training programmes, such as minimum qualifications for tutors and assessors, and special resource requirements.
